I would say not likely. As industries mature, incumbents acquire enough of an advantage that they don't get outcompeted, you just want until the market for their product disappears.

It's like asking if Coca-Cola, Nabisco, or Unilever are going to get "taken down a notch". No, not really. Also "take down a notch" is some pretty judgmental phrasing, as if it implies they're bigger than they deserve to be, as if they're doing something wrong.

Google owns search, Amazon owns retailing, Microsoft owns enterprise, and Apple owns hardware. Every market has a runner-up as well in terms of profitability (arguably Bing, Wal-Mart, Google Cloud, Dell respectively), but that's in the same way Pepsi is the eternal runner-up to Coca-Cola.

These markets are pretty mature now, in ways that they weren't in the days of Yahoo and AOL. In contrast, IBM was dominant for decades and only declined as eventually consumer PC's disrupted mainframes. So really you'd have to ask, what could ever fundamentally disrupt/replace search, online shopping, office software suites, or phones/laptops? It's pretty hard to imagine until something like generalized artificial intelligence comes along.
